Found this Church relatively easy. Did not realise before I visited that it had a small exhibition and you could enter the crypt. Got interested in this Church after learning the story about Lidice and I planned to visit both places on our four days at Prague. My partner did not know about the connection with Lidice and we nearly didn't visit, due to a lack of time. The cost of entry was 150 Kc, bargain!
The exhibition had all the information on boards on the wall and there were a few leaflets and books for sale. It was awsome and quite moving. When we left the Church, my partner told me about a film he'd seen years ago that he thought was about the Germans and the Polish and he realised that this was the actual Church in the film. As soon as we arrived home I ordered the film 'operation daybreak' and that put the icing on the cake. I must admit to not knowing much about the story of 'operation Anthropoid', but we came home from Prague more informed, thanks to our visit.
We will return to Prague and will definately visit again. Brilliant!
